I am really want to ask when could you release the hector_quadrotor for melodic. when I run this file spawn_quadrotor_with_downward_cam.launch, there are always some mistakes. can you fix it? for example there is a error like this :
unknown macro name: xacro:quadrotor_plugins None None
when processing file: /home/kang/hector_quadrotor/src/hector_quadrotor/hector_quadrotor_description/urdf/quadrotor_downward_cam.gazebo.xacro

Thanks for your help.
Actually there is no limitation to build hector_quadrotor for melodic from sources. This link to article with general installation steps may be helpful: Flying with ROS and Hector.
